Th(l forward axle 8 of the locomotivefleiiigr loosely or slidably ioiirnaled within' the blocks 9 carried by the depending or vertical supports 3, it will be seen lat;

eral movement of the forward end ofthe locomotive isprovidedduring lthe travel of the locomotive over a curved section of' track, such movement causing the segment 18 carried thereby to bodily move laterally; with respect to thestationary v rack 17 into which it meshes thereby causing the saidsegment to partially rotate for imparting a `caused by a like movement on the part of that the form of my inventio the forgva'rd end of the locomotive Willimpart b'odily lateral, as well :1s-rotary movement to the 'segmentalrack 18; that move-A ment of the said. rack-18 will in turn partially rotate the headlight 20,.-the rotation of the`latter being governedaccording to the curvature of the track over which the loco-' motive is traveling; and that by providing a. slot 15 of greater length than the Width of the carriage extensions 14, movement of the beam 16 is limited. Y

In reduction to practice, I have found ,illustrated in the drawings and referred to in the above description, as 'the preferred embodiment is the most efiicient and practical; yet realiz-v ing that the conditionsjconcurrent with the adoption of my device will necessarily vary, I desire to emphasize thefact that various minor changes in the details of constructin',f.

proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my inven tion, as defined'in the -ap ended claims.

Having' thus fully described my invention, what I claim as new and desire to secure by Letters Patent, Ais z- '1. In .combination with a locomotive, a relatively movable head light, a bodily. mov-"- able support carried by the'froht'axle of th'e vlocomotive, and a lmovablecarriage mounted upon saidaxlc, and means upon said carriage adaptedl to engage'means upon said" support to shift-the said light Ythrough movement of the support, as and forlthV purpose'set forth.
